CHAP. 35. To find the Visible latitude of the, Moon at the beginning and end of the Suns Eclipse.

FOr the beginning, adde to the minutes of Incidence the motion of the Sun agreeing to the time of Incidence, and the summe sub∣tract from the true motion of latitude at the time of the visible Sy∣nod, so have you the true motion of latitude at the beginning, by which find the true latitude, and by these according to the second rule of the 32 Chapter, may be had the visible latitude.
